The scale of Fig. 1 is greatly reduced from actual size, the size of forming-core 10, and consequently of all related parts, being larger or smaller according to the size of tire required. Figs. 2 to 7 inclusive arel to a scale one and six-tenths larger than that of Fig. 1. Figs. l8 to 17 and 19 and 20 are to a scale twice that of Fig. 1. Fie. 18 is to a scale four times that of Fig.' 1 and Fig. 21 isto the same scale as Fig. V1.

For convenience of description the machine of the present invention may be di.- vided into several coacting sub-mechanisms and to that end the machine will be considered as it operatesrin consecutively advancing the cordsfrom Jfheirsource of `supply to their 'delivery and seating .about the forming-core. y Y y General desmc'ptz'o'n.-The principal mechanisms of my improved machine are grouped about an annular forming-core 10, preferably arranged in a horizontal plane and having 'axial shaft 11 upstanding vertically therethrough. Said Yprincipal mechanisms, because Ythey are required to operate at all points about the circumference of said corev 10, are conveniently divided into a plurality of duplicate segmental portions, all the segmental portions of any one kind uniting to form a complete circumferential mechanism. For convenience of illustration said mechanisms are Vshown as quadripartite, but might with equal propriety comprise more parts-Y or possibly less. Each set of quadripartite mechanismr isaduplicateA of each of the other Y three ofitskifnd and all operate in unison, so that each sub-operation is v,carriedon throughout the whole circumference at one time. Y e a -V f Motion is transmitted to the various sub- VYmechanisms at the proper times, Vthrough shafting,gearing, cams, intermittent trans-f `mission and the like, all from main shaft 12,Fig.1, which, by suitable known means connected with gear 7 but not shown,Y

which in turn drive cutter gears 77. Cutters 75 normally stand idle, with their overhanging eccentric portions projecting outwardly away from slot 67, Figs. 8 and 9, and those cutters must not rotate to cut off the cords until piston 65 has seated those cords in former 28. However, there is no objection to said cutters rotating idly at any Vother time and for convenience and in the sitions, respectively, of Figs. 8 and 9. But

immediately piston 65 reaches its inner position, clamping the cords against former 28, the toothed portion of gear 79 will engage the toothed portion of intermediate 81 and `cause critters 75 to make'about one rotation each in clockwise direction thereby severing the cords. Said gear 79 and cutters 75 are shown midway their oA erative action in Fig. 10. During the retraction of piston 65, from the position of Y10 to that of Figs. 8

and 9. this operation will be reversed and y the cutters returned to their idle positions of said Figs. 8 and 9.

Fig. 11, roll 87, p' fatally mounted in hubs 137 of one of ears 30,7engages cam 40. 'i`he oscillatory7 movement of arm 54 in anti-clockwise direction from the position of Figs. 8, 9 and 10, in connection with the movement of roll 87 I angularly upward in cam 40, from the position of Fig. 16, causes cord-former 28 to move upwardly in a helical path to the pov sition of Fig. 11.

Cord-laying mechanism- This mechanism is'pa'rticularly shown in Figs. 3, 6,- 9,

11, 12 and 14 to 18inclusive. Said mechanism comprises, primarily, four sets of cordlayers, indicated in a general way by 60, each set arranged in curvedrformation in plan view, Figs. 1 and` 15, in conformity with former-core 10 aboutwhich they -fold for delivering the cord thereon. in Fig. 1 the upstanding cord-layers are shown broken Voff close to their bearings, respectively.

Each of said sets of cord-layers is mounted on a carriage, as 88, for reciprocationon portion Vthe next adjacent shortl shaft 94.

table 25 toward and from former-core 10. Said carriage at its inner end has upstanding therefrom opposite brackets 89, 89 carrying segmental table 90 on which are mounted bearings for cord-layers 60. Said cord-layers comprise a set of upper members 6 and lower members 60". The arm portions 'of said upper layers 60a extend upwardly to the right at an acute angle to the horizontal line of the bearings andthe arm portions of said lower layers 60h extend downwardly to the left at anacute angle to the horizontal line of the bearings, Figs. 17 and 18. Each of said members 60- and 60b includes an arm portieri 91 of curved contour near its axis, to conform to the cross-sectional profile of former-core 10, and straight at its outer end. to deliver the cords to the Vcord-end-grippers 109, 101, Fig. 14. `Said arm portions arepreierably provided with small pins 120 projecting from their Vinner faces to engage the sticky cords carried by cord-formers 28, to insure the removal of the cords from said cord-formers by the cord-layers. Y

It will also be observed that the arm-por- Lions of those cord-folders 60, at the opposite ends of. each quadripa 1tite section are materially wider than 'those folders there be tween. This is because of the space required for gearing and the like between adjacent sections of said folders. Arm portion 91 is provided with a back rib 92, Fig. 18, terminating in hub 93 having outstanding horizontally from each side thereof a short shaft 94 terminating in one member 95 of a universal joint for engagement with asimilar universal joint member onthe end of Said short shafts 94,-extending oppositely from :inf-fone hub 93. are in axial line, but the pair` of such shafts extending oppositely from the next adjacent hub 93 have their common axis at a slight angle in the horizontal plane t0 said first mentioned pair to conform to the general curved arrangement of said cord-layers, Fig. 15. To prowide for such angular arrangement, said universal joints are interposed as described. lt will thus be seen that each of the bearings, as 96, will be bored from both ends in one horizontal plane but at a slight angle to each other. Said bearings arepreferably parted theirhorieontal axial plane, and the two halves of the upper box 97 and the two halves of the lower box 96 may be all bolted to segmental table 90 by one bolt 98, Figs. 17 and 18. Said short shafts 94, coupled together by universal joints 95, terminate at their right hand ends, Figs. l5, 17 and 18, in intermeshing gear segments 99, and the upper line of saidshort shafts terminates at its left hand-end, Fig. 15, in universal joint 102, by which it is connected to bevel gear 103 meshing with bevel gear endof shaft are carried by `bracket 106 Y Xed to the side of one of brackets 89 of carriage 88. Near the outer end of 'carriageV 88 and at both sides thereof, fixed to table 25, are several upstanding bearings 110, 111, 116, 120, for shafts and gearing `for operating, back and forth, carriage 88, and for oscillating shaft 105 at suitable times.

For actuating carriage 88, opposite racks 107 are fixed to the upper face thereof and are engaged by gear segments 108, respectively, ixed'to shaft 109 turning in opposite bearings 110. Said shaft 109 is` coupled at its opposite ends by universaljoints to other like shafts 109 by which motion is transmitted to the other three k.carriages 88 and by one of which shafts motion is transmitted from .the main ,driving train tv be described later herein. Oscillating shaft .110,5 is supported at its outer end by'bear'ing 111, in which bearing rotates bevel y,gear 112, through which said shaft may slide .end-

wise and is constrained to vrotation there- Said bevel g`gear K4112V with by key 113. l mesheswith similar bevel gear V114 fixed to one end of shaft 115 turning'in opposite bearings 116. Also fixed to shaft 115 is gear segment 117 meshing with similar segment 118 iXed to shaft 119y adjacently'supported in bearing 120. Said shaft 119 receives its power from the main driving train.

Oord-end seat/ng mechanism--Thismechanism is particularly shown in Figs. 2, 3, 6, 14, 15 and21 and includes means for' gripping those ends 13a and 1-3b of the cords projecting above and belowy cord-layer arms 60'd and 60", respectively,Fig. 1,2,- seev also Figs. 6 and 14; and means fory pressing those ends into the circumferential `grooves lying `between the inner boundary of' the vtubular portion of forming-core 10 and fillerrings 121.

Forming-core 10 as made up ofa plurality of sector-like members preferably four yin number, 10, 10b, 10c and 10d, Fig.y 21, tov

permit the disassembling of'said core for the removal intact .of the laid-up cords thereon. Saidmembers have inwardly-reaching flange-portions, as 122, against the upper and lowerfaees of which arey fastened rings 123 to hold said members in assembled condition. Said flange-portions 122 have their inner faces slightly angled, outwardly downwardly, for snug engagement with ring `r supported on legs unstanding from 124 bedi-plate 45. After lifting corel()` from its seat en ring 124 and removing it fromthe machine, liller-rings 121, which `may be held to their7 seats, respectively, by friction, .may be taken off and then rings 123 may be removed, thereby permitting member 10d,

Also fixed to said shaft 153 is arm 154 conne-ted by link 155, below bedplate 45, with operative means to be described later herein.

For pressing ends 13a and 13b of cords 13 into the circumferential grooves between forming-core 10 and filler-rings 121 and seating in the annular pockets thereby formed, bead-rings 156, respectively, the following means are provided. Said beadrings 156 yare continuous rings, preferably of twisted wire, to furnish the required strength for the edges of the tire or casing, which are engaged by the wheel-rims in seat ing the tire on the wheel. Said bead-rings are carried by upper and lower bead-ringspiders 157 and said spiders may be provided with holding-means such as pins 158, Fig. 14, projecting from their faces, respectively, for penetrating between the wires of said bead-rings.

Upper-spider 157 is removably attached to carrier 162 by interrupted ring joint 163. Figs. 3 and 4, and said carrier isslidably mounted on axial shaft 11 and is prevented from turning thereon by key 164. Lower spider 157 is preferably integral and is slidably mounted on axial shaft 11 and is prevented from turning thereon by key 166. Said spider 157 is provided with openings for legs 125, links 151, 172, arms 54 and such other members as may require passage therethrough. Fixed to opposite shafts. as 134, are two pairs of opposite eccentrics, respectively, as 159, 160. The straps of the inner eccentrics, as 159, are pivotally connected, as at 161, with the undersideof upper-spider-carrier 162, and the straps of the outer eccentrics, as 160, are pivotally connected, as at 165, to lower spider 157. Said eccentrics are set diametrically opposite to each other and if rotated one half rotation, preferably in'clockwise direction, Fig. 3, upper spider 157 will be raised and lower spider 15,7 will be lowered, from the positions of Fig. 3 tothe positions of Fig. 4, respectively. 1f then said e centrics be rotated in anti-clockwise direction back to the positions of Fig. 3, said spiders will be returned to their positions of Fig. 3. For

thus oscillating said eccentrics the followi ing means are provided: Fixed to shaft 134, adjacent eccentric V159, is gear-segment 167 in engagement with gear-segment 168, of twice its radius, fixed to shaft .169 supported in 'fixed bearings 170 springing from table 124. Also fixed to said shaft 169 is rockarm 171 connected by link 172 with one arm of hell-crank 173 pivoted at 174'in a bearing upstanding from hedplate 45. The other arm of said bell-crank 173 is connected by link 175 with means for rocking bell-crank 173 and arm 171, each through a quarter turn and back again.

Driving mecfzrmism.-This mechanism is articularl shown in Figs. 1 and 7 and some of its means for connecting with operative parts of the machine in Figs. 3, 8 and 15.

rThe several shafts of the driving mechanism are carried in suitable bearings, as 176, 177 and 178 of main shaft 12, and said bearings may be supported from fioor 41 by legs and the like, not shown, but of well-known character, said supports being omitted in the interest of clarity. Fixed to shaft 12 are a plurality of cams having grooved paths efficient when shaft 12 is rotated to impart to several short shafts'oscillatory movement through the interposition of suitable arms having rolls thereon for engagement with said grooved paths. A characteristic grooved path 179 is shown in cam 180 and comprises alternate portions of angularly and circumferentially disposed path, respectively. Shaft 181 has arm 182 fixed thereto and carries roll 183 for engagement with cam 180. Also fixedto shaft 181 is gear-segment 184 meshing with small gear 185 iixed to shaft 186. rEhe throw of cam 180 is adapted to oscillate segment 184 in anti-clockwise direction one eighth of a revolution thereby imparting to gears 185 and 187 one full revolution in clockwise direction and to gear 188, meshing with gear 187, one full revolution in anti-clockwise direction. Shaft 189,-to which gear 188 is fixed, has also fixed thereto arm 190 carrying roll 191 for engagement with cradle .During the first quarter of its revolution in anti-clockwise direction, roll 191 will rotate cradle 192 one quarter revolution in clockwise direction and also gear segment 193. said cradle and gear segment being both fixed to shaft 194. Gear segment 193 will therefore rotate gear 195, fixed to shaft 109, one half revolution in anti-clockwise direction, and segment 196 will engage the coacting'portion of cradle 192 to hold the adjacent gearing at rest during the next two quarters oi the described revolution of 188. lVhen gear 187 has made three quarters of a revolution the roll in the end of its arm 197 will engage slot 198 in cradle 192 and turn that cradle and segment 193 in anti-clockwise direction, whereby gear 195 and shaft 109 will be rotated one half revolution in clockwise direction back to their original positions, respectively. During this time main shaft 12 will have made one half a revolution and have stopped, thus completing one cycle.

During the next half revolution of shaft 12 segment 184 will be rotated in clockwise direction through one eighth of a turn, thereby turning gears 185, 187 a full turn therewith are equal gears 205, 206 each hav-` Lesegesa in anti-clockwise direction and the rollv yon arm 19'? will rotate cradle 192 and segment 193 one quarter turn in anti-clockwise direction, the same as before. Then roll 191, during the last quarter of its movement about shaft 189, will return cradle 192 and segment 193 in clockwise direction throughk a quarter turn. Thus the result on segment 193 and gear 195 is the same, no matter in which direction segment 184 moves. ing gears 187, 188 and forming one train ing roll-bearing arms for engagement with cradle 199 fixed to shaft 119 and which mechanism is efficient to impart to shaft 119 a quarter turn in.clocli;wise direction and then a quarter turn back again as Yalready described in connection with cradle 192 and its mefhanism. lt will be observed that shaft 119 will not be actuated until after shaft 109 has made vits half turn and stopped. This is because shaft 109 actuates the cord-layer carriage forwardly for positioning the cord-layers relatively to lcore 10 and thereafter shaft 119 rotates a quarter turn to fold those cord-layers about said core.

Second cam 200, having a grooved path, not shown, similarto the 'grooved path in cam 180, is efhcient, through arm 201 and' and meshing with gear 208 carries arm 211l and gear 208 carries arm 212. These have rolls for engagement with cradle 213 fixed to shaft 214, to which is also fixed'large `gear 215. Gear 217 fixed to shaft 6 8 is con nected through intermediate gear 216 with gear 215 of four times its size. By this lmechanism shaft 68 is rotated one fullrevolution in anti-clockwise direction and then back again during a half revolution of nism operated by cam210. This isbecause the cord-grippers 100, 101 operated from cam 210, must operate before bead-ring spiders 157, operated from cam 220. 'n

' For oscillating bevelr gears 49 and 53, near the foot of axial shaft 11, the followingmeans are provided: lifeshing with bevelL 235 connected byintermediate gear 236 with f gear 237 iixedto lone `end of tubular shaft 238 havingv its bearingonshaft225; ATo .the other end of tubular'shaft 238 is fixed gear 239, connected by intermediate gear 240 with e e gear 241 fixedto the end of shaft 242. Near the other end of shaft 242 isv fixed gear 243 meshing with gear 244,'fixedto shaft 245 carrying arm 246 having a roll in engagement with a cam, not shown, similar to cam 230 and fixed Fig. 7.

Shafts 234 and 242 might well beone continuous shaft, dispensing with the offset to shaft 231k behind cam 230,'`

gearing t0 tubular'shaft 238 except that one y *of cams 40 lies in the path of said shaft, Vand shaftl 225 and tubular sh aft 238 pass thro gh the lower wall of said cam, Fig. 16. Operation. #The operation of my improved 'machine isv as follows: For clarity and yccntinuitykeof description, the several steps in operation will follow the advancement of the cords from their introductiony over rolls 19, 20, 21 and 22 and thence over rails 23, and "so on, `until their delivery and seating on forming-core 10 and the removal of 'that core from the machine.

' The leading 'ends of the cords are presented to the machine overrolls 19 to v22inclusive andy thence positioned yover rail 23 ready to be clamped to the cord-formers 28. Said cord-formers, after kbeing retracted horizontally from engagement with cord-layers 60, by means of links'k 63, Fig. 12, are carried helicallv downward by arms 54, being to the position of l*`ig.,13,"and y'during that downward vmovement clamps29 lying be-.`

wardlyby the engagement yof the ball-ends of the faces ofjcord-formers 28. -Saidcordformers with `the cord-ends gripped thereto continue their downward movement, drawing over rolls A19 to 22 and rails 23,sufficient lengths of cords,l respectively, to reach -an,

Vgularly downwardly over the faces of lsaid* guidedby rolls 87 in vcams 40, respectively, n

4hind the cord-ends in Fig. 1:2 are swung upof with cams34, respectively, and y I fclampthoseends against the lower portions'y t will be observed that the timing of the 'mechanism operated from cam 220 is set for one quarter of a. revolution of thecradle operating arms later than that of the mechal' cord-formers, Fig. 9. Thereupon cord-pistons move from their' positions of Fig. 9 to those of Fig. 10, respectively, and press the cords into the grooves in the vertical portions 28a and 28b and into the dished portions 28C, respectively, Fig. 10,thereby drawing over rails 23 a further portion of cords. Directly after the cord-pistons have seated the cords in the grooves ot the cord-formers, eccentric cutters 7 5 rotate effectively to sever the cords opposite slet-s 67 in the upper portions of cord-formers 2S, respectively. The

severed cords being novv firmly seated in the cord-ormers, cord-pistons 65 Withdraw from the position of Fig. 10, and the cordformers, oscillated by arms 5% and directed upwardly by their rolls 87 in cams 40, respectively, rise in helical paths to the level oi'f the cord-layers, respectively, Fig. 11. luring this upward travel of said cord- 'ormers the ball-ends of arms 36 engage cams 88 and swing clamps 29, respectively, from engagement With the cord loiver ends and leave those clamps in position 'for clamping the next increment oi"4 cords to the cordormers as those ormers descend, as already c escribed. Next, links 63 push theV cordorniers outwardly, delivering the cords therein onto the faces of cord-layers 6() Where they are retained by pins 120', Fig. 9. Then said cord-formers Withdraw from the position of Fig. 12 and descend from in front of said cord-layers to in front of the cord-pistons, Fig` 9.

lThereupon carriages 88, on which are mounted cord-layers 60, respectively, ar moved inwardly toward core 10, and those cord-layers each swinging a quarter turn, lay the cords in parallel angular positions, respectively, about the outer half of core 10 and lay the projecting ends 13a and 13b of the cords against the upper and lovver faces of liller-rings 121, respectively,lFig. 6. It is customary and preferable to cover core 10 with a thin sheet of unvulcanized and more or less sticky rubber, not shown, before delivering the cords thereon, to provide a lining for the casing. Then cord-endgrippers 100, 101 move into engagement with said cord-ends and grip them against filler-rings 121, respectively, Fig. 111.

The cords, now being in possession of the forming-core and its gripping mechanism are released by the cord-layers which open and retract with carriages 88, respectively, to the position of Fig. 11 ready to receive another increment of cords. During this retirement of cord-layers 60, bead-ring spi# ders 15'?, having been previously supplied with beadrings 156, respectively, deliver those bead-rings against the bight of the cords and press the cords into the annular channels adjacent the peripheries of iillerrings 121, drawing the cords tightly about core 10, as the cord-ends are pulled from the grip of end-grippers 100, 101, respectively, Fig. 3. Gripgers 100, .101 and spiders 157 then retract to the positions, respectively, of Fig. 6, leaving bead-rings 156 seated in place, and the operation of laying one set of cords is, completed.

Core 10, having a cf'xntinnous layer of angularly laid cords lthereon With their ends held in place by bearr -rings 156 is then ready 'for removal from the machine. Such removal is accomplished by unlatching upper spider 157 from its carrier 162 and lifting' said spider vertically oil from the machine; then upper end-gripper 100 is similarly unlatched and lifted ofi'. This leaves core 10 free to be par ed from its seat on ring 124, from whence it may be lifted up, over Web 12'? and carrier 162 and so oil the machine.

1f only one layer of cords is desired,lller lrings 121 are then removed, the holding means 'for rings 123 released and those rings removed. This permits segment 10d of core 10 to be Withdrawn and thereafter the other segmental portions oi core 10, 21. @n the other hand, if it is desired to lay one or more additional layers of cords as 13, Fig. 19, over the one already laid, the core is removed from the machine as de scribed but said core is not dismantled. However, filler-rings 121 are removed to provide space between the ends of the cords already laid. and the outer edges of rings 123, respectively. for the ends of the next layer of cords. For assembling and laying said second layer 13C, a machine which is a substantial dus ate of the present one is employed, the only essential difference being that the angular inclination of the showing of 16 and the coacting parts in other iigures would be reversed, so as to lay the second layer of cords cross-Wise to the first layer, Fig. 19; and that cordelayers 60, cordformers 2S and their coacting mechanism would be enough larger to accommodate the slightly increased size of core 10 due to there being one layer of cords thereon; also the operative faces of spiders 157, instead of being adapted to carry bead-rings 156, would be formed to tuck in the ends of cords 13.
